Stimulation of cellular signaling and G protein subunit dissociation by G protein betagamma subunit-binding peptides.


We previously developed peptides that bind to G protein betagamma subunits and selectively block interactions between betagamma subunits and a subset of effectors in vitro (Scott, J. K., Huang, S. F., Gangadhar, B. P., Samoriski, G. M., Clapp, P., Gross, R. A., Taussig, R., and Smrcka, A. V. (2001) EMBO J. 20, 767-776). Here, we created cell-permeating… (More)
